The Arshakid kings' mausoleum is located in Aragatsotn region in the village of Aghtsk, where the remains of both pagan and Christian kings were placed. This small, rectangular hall is truly remarkable for its decorative and thematic elements. The northern wall depicts a relief of Daniel in a lion den. There are also many ornaments and symbolic carvings, belonging to both pre-Christian ideas and Christian art. Just next to the mausoleum there are the ruins of a 4th century church.
